Course: Introduction

According to the UCR definition, criminal homicide is the willful (nonnegligent) killing of one human being by another.


Criminal homicide is the taking of another person’s life by an individual through unlawful means. The Uniform Crime Reports (UCR) Program, which is administered by the Federal Bureau of Investigation (FBI), defines criminal homicide as the willful killing of one human being by another, including murder, non-negligent manslaughter, and negligent manslaughter. Homicide is one of the most serious criminal offenses and carries severe penalties, including imprisonment, fines, and in some cases, the death penalty.

Murder is the most serious form of criminal homicide and involves the intentional killing of another person with malice aforethought. Malice aforethought refers to a deliberate intent to kill or cause serious bodily harm to another person. Murder can be classified as first-degree or second-degree, depending on the circumstances of the offense. First-degree murder involves premeditation and planning, while second-degree murder is typically a crime of passion or impulse.

Non-negligent manslaughter is another form of criminal homicide and involves the killing of another person without malice aforethought. Non-negligent manslaughter can be classified as voluntary or involuntary. Voluntary manslaughter involves the intentional killing of another person in the heat of passion, while involuntary manslaughter involves the unintentional killing of another person as a result of criminal negligence or recklessness.

Negligent manslaughter, also known as criminally negligent homicide, is the least serious form of criminal homicide and involves the unintentional killing of another person as a result of criminal negligence or recklessness. Negligent manslaughter typically involves situations where an individual fails to exercise reasonable care or caution, resulting in the death of another person.

The UCR Program collects data on criminal homicide offenses from law enforcement agencies across the United States. Homicide offenses are classified into two categories: murder and non-negligent manslaughter, and negligent manslaughter. The UCR Program also collects data on the circumstances surrounding the homicide, such as the relationship between the victim and the offender and the use of a weapon during the offense.

In addition to the classification of homicide offenses, the UCR Program also collects data on the clearance rate of homicide offenses. The clearance rate is the percentage of homicide offenses that are solved by law enforcement agencies. The clearance rate for homicide offenses is typically lower than for other types of offenses, as homicide investigations can be complex and require significant resources.
